Baketown Scotty

Installed 190 main jets. It ran fine and continued to run fine with choke pulled too. I'll keep going up.

It is just for me playing in the sand. I'll get the mains then start fooling with the needle to get mid range dialed in. Thanks for the comments and all the help.

I did a plug chop after running the 168 mains and everything was still clean and shiny. Installed 178's last weekend and ran good with a very slight hesitation in the middle. Looked at the plugs, still looking shiny and new. I will chop them when I get back home this weekend. Also going to go bigger on the main jets and try that. It was 95-100 degrees last weekend so the added heat may have had some effect. I'll keep going bigger until I start fouling the plugs?

I have not done a plug chop. I will be home this weekend and will do one. Thanks for the help.

I started with the pilots at 42, then 45 and ended at 50. Starts easy, idles and no hesitation from 0 up. With the mains I started at 158, then 160, 162 and 168 today. Ran great through all gears, even pulling good in 6th. Pulled the new plugs after WOT and they are looking pretty shiny. Should I continue going larger with the mains until I get it too rich? Or should I be looking elsewhere?

OK, will do. Is that to help them get fuel mixture evenly to each?

Anybody have an idea where I can find some rubber caps to put over the brass outlet in the front of my 28PWK carbs?

Thank you very much for the help.

Replaced my 26mm Mikuni carbs with 28mm Keihin carbs and would like some help with a starting point for jetting. 95% of all riding is in sand dunes, Pismo, Dumont and Glamis.

That's my question 6) What size main jets are you using? Thats my question 7) What temperature is your Banshee jetted for? It needs to be 70 - 100 8) Do you have a port job? Yes, I'm told it was a mild dune port job. 9) What kind of carbs? Keihin 10) What size carbs? 28mm Thank you
